Description

Technical Field

[0001] The present invention relates to the technical field of wireless power supply, and more particularly to an overhead line power supply and equipment fixing device. Background Art

[0002] In the 750 kV UHV AC transmission system, overhead line power supply and equipment fixing devices are key technologies to ensure reliable line operation. The CT electrical device draws energy from the conductor current to achieve wireless power supply needs and converts high voltage into low voltage. Secondly, the CT electrical device needs to be fixed on the overhead line bracket to achieve the stable power supply requirements of the CT electrical device.

[0003] In existing public literature, patent publication number CN106972640A discloses a line-sensing power-taking device. This technology utilizes a dual torsion spring for resetting the upper current mutual inductance sensor, which is mounted on two pins. The upper force-applying arm of the dual torsion spring presses against the top of the upper current mutual inductance sensor. A dual torsion spring for pressing the wires is mounted on two fixed shafts, and the lower force-applying arm of the dual torsion spring presses against a groove in the lower housing. This line-sensing power-taking device can be installed live and does not affect the use of the power grid. However, this technology still presents the following issues.

[0004] In the 750 kV UHV AC transmission system, the overhead line power-taking equipment needs to be fixed and then draw power through wireless inductive coupling. However, in actual use, wind pull can easily cause the locking parts of the overhead cables to loosen, and the position of the overhead cables to shift, making it difficult for the power-taking equipment to automatically adjust to the same center as the overhead cables to draw power. Moreover, once there are a lot of impurities on the overhead lines, it is difficult to adjust the power-taking equipment according to actual needs, which will affect the power-taking effect. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: an overhead line power taking and equipment fixing device, comprising a CT power taker and a wireless controller, one side of the CT power taker is fixedly connected to a linkage rod, the outer wall of the linkage rod is provided with an adjustment power taking assembly; the adjustment power taking assembly includes a sleeve slidably connected to the outer wall of the linkage rod, and an arc-shaped support plate is installed on the outside of the sleeve, the inner wall of the arc-shaped support plate is provided with an arc-shaped tooth groove, and a linkage frame is installed on one side of the arc-shaped support plate; a linkage block is fixedly installed on one end of the linkage frame, a rack is fixedly connected to one end of the linkage block, the inner wall of the rack is slidably connected to a guide rail, the outer wall of the rack is meshingly connected to a gear, and a reduction motor is installed on one end of the gear.

[0006] Preferably, the sleeve is slidably connected to the arc-shaped support plate to which the arc-shaped tooth groove belongs, and the linkage frame is slidably connected to the sleeve. The linkage block is slidably connected to the guide rail, and the guide rail is fixedly connected to the arc-shaped support plate; the reduction motor is used to drive the gear to rotate, and the reduction motor is electrically connected to the wireless controller. The top of the arc-shaped support plate is fixedly connected to a fixing frame, and the wireless controller is fixed on one side of the fixing frame. The outer wall of the CT electrical appliance is clamped with a clamp, and the inner wall of the clamp is installed with a locking bolt; an overhead line is installed inside the CT electrical appliance. A pillar is fixedly connected between the reduction motor and the guide rail, and the pillar is used to support the reduction motor. The top of the rack is fixedly connected to a limit plate, and the arc-shaped support plate and the guide rail are both slidably connected to the limit plate.

[0007] When this technology is in use, the reduction motor drives the gear to engage and rotate. The rack drives the limit plate to start rotating, and the rack drives the linkage block to rotate clockwise. The linkage frame moves the sleeve, and the sleeve moves along the arc-shaped tooth groove path inside the arc-shaped support plate. The sleeve drives the linkage rod to move along the path of the arc-shaped tooth groove, and the linkage rod drives the CT electrical appliance to move along the path of the arc-shaped tooth groove, so that the CT electrical appliance can move along the path of the arc-shaped tooth groove on the outside of the overhead line, so that the CT electrical appliance can move at different angles according to different guide distance positions of the tooth groove. When the distance values sensed by the two laser distance sensors are the same, and the distance values sensed by the two laser distance sensors are the same as the distance values set by the wireless controller, the reduction motor is turned off by the wireless controller.

[0008] Preferably, two inclined support blocks are fixedly connected at the corner line position of the inner wall of the CT electrical collector; a tilting ring is fixedly connected to one side of each of the inclined support blocks, and a laser distance sensor is fixedly installed on the inner wall of the tilting ring; a support sleeve is fixedly connected to one side of the CT electrical collector and away from the position of the tilting support block, and a camera is fixedly installed on the inner wall of the support sleeve, and the camera and the laser distance sensor are both electrically connected to the wireless controller.

[0009] When this technology is in use, the support sleeve supports the camera, which observes the power supply area between the overhead line and the CT power supply. The wireless controller can wirelessly transmit the video of this area to the backend remotely. Two laser distance sensors are used to measure the distance value of the outer wall of the overhead line. When the distance values sensed by the two laser distance sensors are different, and the distance values sensed by the two laser distance sensors are different from the distance value set by the wireless controller, it is known that the overhead line and the CT power supply are out of center.

[0010] Preferably, the outer wall of the linkage rod is fixedly connected to a sleeve near the location of the CT power supply; the sleeve is fixedly connected to the CT power supply; a support ring is slidably connected to one side of the linkage frame, which is fixedly connected to the sleeve; guide bars are fixedly connected to the top and bottom ends of the linkage rod, and both guide bars are slidably connected to the sleeve; a sliding ring is slidably connected between the linkage frame and the curved support plate, and another sliding ring is slidably connected to the other side of the curved support plate, and both sliding rings are fixedly connected to the sleeve; one end of the linkage rod is fixedly connected to a push block, and a micro-electric cylinder is mounted on one side of the push block, the support ring is fixedly connected to the micro-electric cylinder, the output end of the micro-electric cylinder is fixedly connected to the push block, and the micro-electric cylinder is electrically connected to the wireless controller. The two guide bars are symmetrically arranged about the center point of the linkage rod, and the outer walls of both guide bars are smooth. The two sliding rings are symmetrically arranged about the curved support plate, and the vertical cross-sections of both sliding rings are circular.

[0011] When this technology is in use, the micro-electric cylinder pushes the push block to the left, causing the linkage rod to move leftward along the inner wall of the sleeve. Two sliding rings on the sleeve contact the curved support plate for positional support. This allows the sleeve to support the support rings, stabilizing the micro-electric cylinder's movement. The sleeve block drives the linkage rod, which can move along damaged or impurity-obstructed areas of the overhead line, enabling automatic lateral adjustment of the CT power supply's fixed position.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention adopts an adjustable power supply assembly. The gear drives the rack to rotate, and the rack drives the linkage block to rotate clockwise. The sleeve moves along the arc-shaped tooth groove path inside the arc-shaped support plate. The sleeve drives the linkage rod to move along the path of the arc-shaped tooth groove. The CT power supply can move at different angles according to different guide distances of the tooth groove, realizing multi-dimensional adjustment of the power supply position of the CT power supply, so that the CT power supply can automatically adjust to the position concentric with the overhead line to supply power. In addition, the CT power supply can be adjustably fixed according to actual needs. Even if there are many impurities in the power supply area between the overhead line and the CT power supply, it can be ensured that the CT power supply is concentric with the center point of the overhead line in real time and draws power without impurities, thereby improving the power supply effect.

[0014] 2. This invention utilizes a tilting support block, a tilting ring, and a laser distance sensor to work together. The tilting support block drives the tilting ring, enabling the laser distance sensor to accurately monitor the distance to the outer wall of the overhead line along the arc-shaped tooth path, ensuring that the CT power supply is concentric with the overhead line. Furthermore, the support sleeve supports a camera to monitor the power supply area and assist the CT power supply in determining the correct direction if damage or impurities are detected. This combination of structures enables real-time monitoring of the power supply status and precise adjustment of the CT power supply position, effectively avoiding damage and impurity interference, ensuring that the CT power supply is always in the optimal power supply position, and improving power supply efficiency and stability.

[0015] 3. The present invention uses a camera to view the power supply area, and the wireless controller can remotely transmit video to promptly detect damage or impurity obstruction in the power supply area. After starting the micro-electric cylinder, the push block drives the linkage rod to make the guide bar cooperate. Under the support of the sleeve limit, the linkage rod drives the sleeve block to move, and then drives the CT power supply away from the damaged or impurity obstruction area to achieve automatic lateral adjustment. This design can monitor and accurately locate the problem area in real time, automatically adjust the position, avoid manual intervention, improve adjustment efficiency and accuracy, ensure stable power supply of the CT power supply, and enhance the power supply effect.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 - Figure 8 An overhead line power supply and equipment fixing device is shown. The overhead line power supply and equipment fixing device is provided with an adjustable power supply component. The setting of the adjustable power supply component can automatically adjust the CT power supply 1 to a position coaxial with the overhead line 25 to draw power.

The specific structural setting of the adjustable power supply component is as follows.

[0027] In this embodiment, if Figure 1 - Figure 6 As shown, it includes a CT power supply 1 and a wireless controller 23. A linkage rod 2 is fixedly connected to one side of the CT power supply 1, and an adjustment power supply assembly is provided on the outer wall of the linkage rod 2; the adjustment power supply assembly includes a sleeve 3 slidably connected to the outer wall of the linkage rod 2, and an arc-shaped support plate 4 is installed on the outside of the sleeve 3, an arc-shaped tooth groove 5 is opened on the inner wall of the arc-shaped support plate 4, and a linkage frame 6 is installed on one side of the arc-shaped support plate 4.

[0028] A linkage block 7 is fixedly mounted on one end of the linkage frame 6. A rack 8 is fixedly connected to one end of the linkage block 7. A guide rail 10 is slidably connected to the inner wall of the rack 8. A gear 9 is meshingly connected to the outer wall of the rack 8. A reduction motor 29 is mounted on one end of the gear 9. The sleeve 3 is slidably connected to the arcuate support plate 4 to which the arcuate tooth groove 5 belongs. The linkage frame 6 is also slidably connected to the sleeve 3. The linkage block 7 is slidably connected to the guide rail 10, which is fixedly connected to the arcuate support plate 4.

[0029] The reduction motor 29 is used to drive the gear 9 to rotate. The reduction motor 29 is electrically connected to the wireless controller 23 .

[0030] In this embodiment, if Figure 5 As shown, two inclined support blocks 11 are fixedly connected at the corner line position of the inner wall of the CT electrical device 1; a tilting ring 12 is fixedly connected to one side of each inclined support block 11, and a laser distance sensor 13 is fixedly installed on the inner wall of the tilting ring 12. A support sleeve 14 is fixedly connected to one side of the CT electrical device 1 and away from the inclined support block 11. A camera 15 is fixedly installed on the inner wall of the support sleeve 14. The camera 15 and the laser distance sensor 13 are both electrically connected to the wireless controller 23.

[0031] In this embodiment, if Figure 1 - Figure 8 As shown, the outer wall of the linkage rod 2 is fixedly connected to the sleeve block 16 near the position of the CT electrical collector 1; the sleeve block 16 is fixedly connected to the CT electrical collector 1, and a support ring 18 is slidably connected to one side of the linkage frame 6. The support ring 18 is fixedly connected to the sleeve 3. The top and bottom ends of the linkage rod 2 are fixedly connected to guide bars 19, and the two guide bars 19 are slidably connected to the sleeve 3.

[0032] A sliding ring 17 is slidably connected between the linkage frame 6 and the arc-shaped support plate 4, and another sliding ring 17 is slidably connected to the other side of the arc-shaped support plate 4. The two sliding rings 17 are fixedly connected to the sleeve 3. One end of the linkage rod 2 is fixedly connected to a push block 20, and a micro-electric cylinder 21 is installed on one side of the push block 20. The support ring 18 is fixedly connected to the micro-electric cylinder 21, and the output end of the micro-electric cylinder 21 is fixedly connected to the push block 20, and the micro-electric cylinder 21 is electrically connected to the wireless controller 23.

[0033] The two guide bars 19 are symmetrically arranged about the center point of the linkage rod 2, and the outer walls of the two guide bars 19 are smooth surfaces. The two sliding rings 17 are symmetrically arranged about the arc-shaped support plate 4, and the vertical cross-sections of the two sliding rings 17 are both circular.

[0034] In this embodiment, if Figure 1 - Figure 4As shown, the top of the curved support plate 4 is fixedly connected to a fixing bracket 22, and a wireless controller 23 is fixed to one side of the fixing bracket 22, so that the fixing bracket 22 can be positioned on the overhead support. The fixing bracket 22 is locked and installed using fixing bolts. The fixing bracket 22 fixes and supports the curved support plate 4 and can also provide support for the wireless controller 23. A clamp 24 is clamped to the outer wall of the CT power supply 1, and a locking bolt 28 is installed on the inner wall of the clamp 24. An overhead line 25 is installed inside the CT power supply 1, so that the clamp 24 is clamped to the outer wall of the CT power supply 1 and tightened using the locking bolt 28. At the same time, the overhead line 25 is located inside the CT power supply 1 to realize wireless power supply processing.

[0035] A pillar 26 is fixedly connected between the reduction motor 29 and the guide rail 10. The pillar 26 is used to support the reduction motor 29. The top of the rack 8 is fixedly connected to the limiting plate 27. The arc support plate 4 and the guide rail 10 are both slidably connected to the limiting plate 27 so that the guide rail 10 supports the pillar 26, and the pillar 26 supports the reduction motor 29. The limiting plate 27 can limit the top position of the rack 8 to prevent the rack 8 from derailing from the guide rail 10.

[0036] The working principle of the overhead line power supply and equipment fixing device of the present invention is as follows:

[0037] First, when performing fixed power extraction in the present invention, the CT power supply 1 is positioned outside the overhead line 25 of the 750 kV UHV AC transmission system. A clamp 24 is simultaneously clamped onto the outer wall of the CT power supply 1 and tightened with a locking bolt 28, thereby locking the CT power supply 1. The fixing bracket 22 is then positioned on the overhead support and tightened with fixing bolts. The fixing bracket 22 securely supports the curved support plate 4, which in turn supports the sleeve 3. The sleeve 3 supports the linkage rod 2, which securely supports the CT power supply 1. In this manner, the CT power supply 1 and the overhead line 25 are concentrically located for power extraction, and the CT power supply 1 performs inductive coupling power extraction.

[0038] Secondly, when the present invention adjusts the fixed position, the CT power supply 1 supports the support sleeve 14, and the support sleeve 14 supports the camera 15. The camera 15 views the power supply area between the overhead line 25 and the CT power supply 1, and the wireless controller 23 can wirelessly transmit the video of these areas to the background remotely. When it is found that the power supply area is damaged or blocked by impurities, these areas will cause problems with the power supply of the CT power supply 1.

[0039] The wireless controller 23 activates the micro-electric cylinder 21, which pushes the push block 20 to the left. This push block 20 drives the linkage rod 2 to the left, and the linkage rod 2 moves leftward along the inner wall of the sleeve 3. Simultaneously, the linkage rod 2 drives the two guide bars 19 to the left, and the two sliding rings 17 on the sleeve 3 contact the curved support plate 4 for positional support, thereby keeping the sleeve 3 stationary. This supports the support ring 18, which in turn supports the micro-electric cylinder 21, stabilizing the micro-electric cylinder 21's movement. The linkage rod 2 drives the sleeve block 16 to the left, which in turn drives the linkage rod 2. The linkage rod 2 can move along the damaged or impurity-obstructed area of the overhead line 25 until it is clear of the damaged or impurity-obstructed area, automatically adjusting the fixed power supply position of the CT power supply 1 laterally. The wireless controller 23 then deactivates the micro-electric cylinder 21.

[0040] Then, when adjusting power supply, if there is a dimensional fluctuation between the center point of the overhead line 25 and the CT power supply 1, the two laser distance sensors 13 measure the distance to the outer wall of the overhead line 25. If the distance values sensed by the two laser distance sensors 13 differ, and the distance values sensed by the two laser distance sensors 13 differ from the distance value set by the wireless controller 23, it is known that the overhead line 25 and the CT power supply 1 are not concentric, and wireless inductive coupling power supply is being used.

[0041] The reduction motor 29 is activated via the wireless controller 23. The curved support plate 4 supports the curved support plate 4, the guide rail 10 supports the pillar 26, and the pillar 26 supports the reduction motor 29. The reduction motor 29 drives the gear 9 to engage and rotate. Simultaneously, the gear 9 rotates the rack 8, which in turn rotates the limit plate 27. The limit plate 27 begins to move away from the curved support plate 4 and the guide rail 10. The rack 8 then drives the linkage block 7 to rotate clockwise, which in turn drives the linkage frame 6 to rotate clockwise. The linkage frame 6 causes the sleeve 3 to move, and the sleeve 3 moves along the path of the curved tooth groove 5 inside the curved support plate 4. The sleeve 3 slides along the inner wall of the linkage frame 6 at the same time, and the sleeve 3 drives the two sliding rings 17 to move along the path of the arcuate tooth groove 5. The sleeve 3 drives the linkage rod 2 to move along the path of the arcuate tooth groove 5, and the linkage rod 2 drives the CT electrical device 1 to move along the path of the arcuate tooth groove 5. In this way, the CT electrical device 1 can move along the path of the arcuate tooth groove 5 on the outside of the overhead line 25, so that the CT electrical device 1 can move at different angles according to different guide distances of the tooth groove.

[0042] The CT power supply 1 drives the tilting support block 11 to move along the path of the arcuate tooth groove 5. The tilting support block 11 drives the tilting ring 12 to move along the path of the arcuate tooth groove 5. The tilting ring 12 drives the laser distance sensor 13 to move along the path of the arcuate tooth groove 5. The two laser distance sensors 13 continue to sense the distance to the outer wall of the overhead line 25. When the distance values sensed by the two laser distance sensors 13 are the same, and the distance values sensed by the two laser distance sensors 13 are the same as the distance value set by the wireless controller 23, the wireless controller 23 turns off the reduction motor 29. In this way, the CT power supply 1 can again draw power at a position concentric with the overhead line 25, automatically adjusting the fixed position of the overhead line 25 to ensure that the overhead line 25 can maintain a concentric position with the center point of the overhead line 25 in real time for power collection, resulting in a better power collection effect.
